Ventricular tachyarrhythmias (VAs) commonly occur early in ischaemia, and remain a common cause of sudden death in acute MI. The thrombolysis and primary percutaneous coronary intervention era has resulted in the modification of the natural history of an infarct and subsequent VA. Presence of VA could independently influence mortality in patients recovering from MI. Appropriate risk assessment and subsequent treatment is warranted in these patients. The prevention and treatment of haemodynamically significant VA in the post-infarct period and of sudden cardiac death remote from the event remain areas of ongoing study.
室性快速心律失常(VAs)通常在缺血早期出现,并且仍然是急性心肌梗死(MI)患者猝死的常见原因。溶栓和直接经皮冠状动脉介入治疗时代已经改变了梗死及随后室性快速心律失常的自然病程。室性快速心律失常的存在可独立影响心肌梗死康复患者的死亡率。对这些患者进行适当的风险评估及后续治疗是必要的。梗死后期血流动力学显著的室性快速心律失常的预防和治疗以及远离事件发生时的心源性猝死仍然是正在研究的领域。
